A costton bud, Q-Tip, slightly moistened, will get the clinging dust off a model. You will use a boat load of them. I have some tiny versions of a cotton bud sold as a paint applicator which will get around the base of struts and wires. A little bit of cotton wrapped around the end of a toothpick will do as well and is much cheaper. I still have a shelf or so worth of models to clean.
